Abstract: The object of this study is the Far East, located in a steadily active transition-contact zone of the two greatest structures of the Earth – the Asian continent and the oceans, and Arctic and Pacific oceans. The subject of this study is the nature of the relationship and interaction of relief formation and substrates (litho-, chion - and phyto -) generated by the three spheres of the physical and geographical shell of the Earth and composing the upper horizons of its solid shell. The goal of this work is to elucidate the multifaceted relationships and interactions between substrates and geomorphological processes in the south and north of the Far East. The data (1955-2011) of the author's research, as well as available literary and stock sources are used. Comparative geographical and information methods were used in the analysis. The novelty of the study lies in the fact that the substrates involved in relief formation in different climatic conditions of the Far East, differ in unique appearance and organization.  Results obtained from original materials, with the relevant data from the literature, can be useful in choosing the strategy for environmental management in all of the areas where it must be utmost "gentle", taking into account existing risks and their identified environmental constraints.

Abstract: The object of this work is the polar landscapes of Eastern Chukotka. The research task is to determine the nature and specificity of geological and geomorphological structure of the territory in typical and anomalous environments of cryolithomorphogenesis. The goal consists in the theoretical and practical studies of sustainability and plasticity of the polar geosystems on the background of climatic changes, amid the conflicting interactions between continentality and oceanicity. Special attention is given to the detailed analysis of morpholythogenic effects of the typical and anomalous (extreme – critical and crisis, as well as disastrous) processes and factors. The main conclusion lies in the following: in the course of development of the northern territories and increased interference in their natural environment, all permafrost processes are activated, with the leading role of thermokarst. Special contribution into the study is defined by the fact that, in the context of the upcoming continentalization of climate and assumed conservation the territory in Eastern Chukotka, the traceable natural risks are reducing, and the geosystems, most commonly, retain their initial sustainability. The exogenous crisis situations and disasters are forecasted, which allows making adjustments to the practice of optimal natural resource management. The scientific novelty lies in tracing the sustainable development of the territory, considering not only the compound, but also thorough complexation of the living and fossil.

Abstract: The subject of this research is the diverse forms of space and time reflection in the development of geosystems (GS). The object of this research is the GS related to space and existing only in time. The author carefully examines such aspects of the topic as space and time, inseparable from each other, and if compared to other characteristics, are the paramount attributes of geosystems (natural, technogenic, and social) in the typical and anomalous environments. Particular attention is given to consideration of "time", characterized by the active (physical) properties influencing the events in geographic space and manifesting in opposition to the normal flow of processes, leading to the destruction of GS. The main conclusions lie in the positions determining the exogenous crisis situations and disasters as predicted. Author’s special contribution is the revealed opportunity to make certain adjustments to the practice of natural resource management considering sustainable development of the territory. The scientific novelty consists in tracing the sustainable development of the territory, which is based on taking into account not only typical, but also anomalous natural processes and phenomena. Because the exogenous crisis situations and disaster are predicted, the practice of natural resource management can be adjusted considering sustainable development of the territory.
